Abstract (en)

[origin: ES8200427A1] The aqueous solution of a statistical terpolymer containing quaternized amino groups and having a regular chemical structure of (a) from 8 to 20%, by weight, of N,N-dimethylaminoethyl acrylate and/or N,N-dimethylaminoethyl methacrylate (b) from 45 to 80%, by weight, of styrene and (c) from 8 to 35%, by weight, of acrylonitrile the sum of (a) to (c) being 100%, by weight, and at least 10% of the dimethylamino groups of the terpolymer being quaternized and the remainder protonated is suitable as cationic paper sizing agent.
